Exciting news! We're transitioning to the Statewide California Earthquake Center. Our new website is under construction, but we'll continue using this website for SCEC business in the meantime. We're also archiving the Southern Center site to preserve its rich history. A new and improved platform is coming soon!

A Reciprocity Method for Multiple-Source Simulations

Leo Eisner, & Robert W. Clayton

Published June 2001, SCEC Contribution #523

Reciprocity is applied to the situation where simulations are needed for a number of source locations, but relatively few receiver positions. By invoking source-receiver reciprocity, the number of simulations can be generally reduced to three times the number of receiver positions. The procedure is demonstrated for a heterogeneous medium with both single force and double couple sources. The numerical tests using a finite-difference implementation show that the reciprocal simulations can be performed with the same level of accuracy as the forward calculations.
